Measurement of the Branching Fraction for the Decay $\psi (3686)\to \varphi K_S^0{K}_S^0$

BESIII Collaboration, M. Ablikim, M. N. Achasov +592

Based on $(448.1\pm 2.9)\times 10^6$ $\psi (3686)$ events collected with the BESIII detector operating at the BEPCII collider, the decay $\psi (3686)\to \varphi K_S^0{K}_S^0$ is…
